当在片段内部添加片段时错误膨胀类片段

问题描述：

我已经添加了片段里面的片段，我得到了如何修复它的错误。我的Java片段类是如下当在片段内部添加片段时错误膨胀类片段

public class MyListFragment extends Fragment { 

IntentFilter filter; 
Toolbar mToolbar; 

MyListAdapter mAdapterlist; 

public static Connections newInstance(int instance) { 
    Bundle args = new Bundle(); 
    args.putInt("argsInstance", instance); 
    Connections fourthFragment = new Connections(); 
    fourthFragment.setArguments(args); 

    return fourthFragment; 
} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    View root = inflater.inflate(R.layout.fragment_my_list, container, false); 

    mToolbar = (Toolbar) root.findViewById(R.id.toolbar1); 
    // mToolbar.setBackgroundColor(getResources().getColor(R.color.white)); 
    // mToolbar.setTitleTextColor(getResources().getColor(R.color.menu)); 
    mToolbar.setTitle(""); 
    ((AppCompatActivity)getActivity()).getDelegate().setSupportActionBar(mToolbar); 


//add this line if you want to provide Up Navigation but don't forget to to 
//identify parent activity in manifest file 

    ((AppCompatActivity)getActivity()).getDelegate().getSupportActionBar().setDisplayShowTitleEnabled(false); 
    setHasOptionsMenu(true); 
    ; 
/* 
    SharedPreferences sharedPreferences = getContext().getSharedPreferences("reg_id", Context.MODE_PRIVATE); 
    String user_id = sharedPreferences.getString("id",""); 
    My_listing obj = new My_listing(user_id); 
    obj.execute();*/ 



     if (getActivity() == null) 
      return null; 
     FragmentTransaction ft = getChildFragmentManager().beginTransaction(); 
     Trends nf = (Trends) Trends.instantiate(getActivity(), Trends.class.getName(),savedInstanceState); 
     ft.add(R.id.fragment3, nf); 
     ft.commit(); 


    RadioButton trends1 = (RadioButton) mToolbar.findViewById(R.id.trending1); 
    RadioButton mine1 = (RadioButton) mToolbar.findViewById(R.id.mine1); 

    final LinearLayout fragment4layout = (LinearLayout) root .findViewById(R.id.fragment4layout); 

    mine1.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 



     } 
    }); 

    trends1.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      fragment4layout.setVisibility(View.GONE); 

     } 
    }); 

    return root; 

}

和布局文件是：

ho解决这个问题

请尝试以下操作：在'onCreateView'中只膨胀您的视图并将其返回。重写'onViewCreated'方法，并从'onCreateView'切割代码的其他部分代码。 – aborocz

答

在您的布局xml中，FrameLayout只能容纳一个孩子，因此您应该将其更改为RelativeLayout或LinearLayout。将您的fragment3更改为FrameLayout以将其用作碎片的容器。

当在片段内部添加片段时错误膨胀类片段
